Application anuary=11,:1,933, Serial No.565L218 This invention relatesto a refilling device for -the reservoir of a-barometric-liquid-feeding device' for -an oil stove or the-like, the general ob- I This invention also consists in certain other -1 features of construction and in the combination and-arrangement of the severalparts to be hereinafterfully'described, illustrated in the accompanying drawings and specifically pointed out in the appendedclaims.

"wherein like characters denotelike or corresponding parts throughout the-several views; and a the-prongs andhas apart thereon for engaging inwhich:-

Figure l is a viewin elevation showingain-installation 0f the-invention.

Fig. 2 is a top plan view of the valve 'carrying memberand cap for 'thelower endof the reservoir or bottle.

Fig. 3 is a section on line 3-'-3*of 'Fig; 2. Fig. 4 is asection on line 4-4- of Fig. 2. In these drawings, the letter A indicates a reservoir or bottle'for an oil stove or the l-i-keand the letter B indicates asupporting "stand-for tle from its supporting means and then take the bottle into the cellar-or other storage room-where the tank containing a'supply of oil is located and 1135 refill the bottle fromthis tank and then carry the bottle back to the supporting means.

It is the object of 'thisinvention to eliminate-- this work of refilling the bottle, and in carryingout the'invention, a small hand pump P is suiti=l ably supported and is connected to the tank T by valve body 3 which has a cap 4 attached to its upper end into which the mouth of the bottle is screwed.

A gasket 5 is placed in the cap to form a tight joint between the mouth of the bottle and the 1:50 cap. The body is formed with a lateral tubular extension 6 having a nipple 7 threaded therein and the tube or pipe 2 is attached to this nipple. A valve 8 has its stem 9 slidably supported by the guide or spider 10 located in the part 6 and a spring 11 normally holds the valve 8 closing lip-describing the invention in -detail, refer-- 'ence willbe had to the-accompanying drawings As is well known, WhEI1"l'/h8b0tt1e needs refilling, it is necessary toremove the 'botthe -inner end of the nipple '7. The body 3 ex- -tends -into the usual'well l2 to'which a-pipe 13 is connected, this pipeleadingthe oil to the burners of the stove. The bodyis provided with ports 14 --in its lower partwhich deliver theoil -from-the body into the well, and-the valve -15 engaging; a seat 16 in the lower part ofthebody prevents oil from passing from the-ports llwhen-the valve is inclosedposition. The stem 17 0f this valve passes through the-guide orspiderl8 and a spring 19 tends to hold the-valveon'its seat.

- The spider 18 isheld-on-its seatby a sleeveZO in-the upper part-of thebody with its upper end in communication with thebottle through the cap. Thelower endof the stem l7 eXtendsintoIsIO the-space between-the prongs -2l-formed bythe forked lower end of the bodyand thehead:23 of a-cam lever -=24is pivoted in the-space between the lower end of the stem 1'7 when-the lever is' upper end of the lever to hold the leverin its outward position. I As willbe seen, whenv the lever 24 is in inoperative position; its handle part-will extend upwardly parallelto the major'portion of the body, with its upperend located in the space formedby aportionof the body andthe latchi member-'25." Then when the valve 15' isto be opened to permit liquid to how from the bottle or reservoir into the well; the latch member 25- is swung upwardlyon its pivot so that-the upper endof the-lever 24 canpass the same-and after the-lever 24 has been moved to-cause its-head to engage the stem of} the valve 15, -to raise M said valve-l5-ofi itsseat; the latch member-254s swung downwardhnso that h the upper-end of the lever 24 will rest against the same and thus the lever 24 is held in a position with a part of its head engaging the stem of valve 15 to hold the valve off its seat. The liquid or oil will then flow from the bottle through the body into the well, but as soon as the level of liquid in the well lol) reaches a point where the port 14 is covered by the liquid, the flow of liquid from the bottle to the well ceases. Thus it will be seen that the device acts as a barometric liquid feeding device.

When the valve 8 is on its seat and the stem- 17 of the valve 15 is raised by the cam lever 24,

the upper end of said stem 17 will abut the end of the stem 9 of the valve 8 and thus hold the valve 8 on its seat and prevent opening movement of the valve 8, so that it one should operate the pump P with the valve 15 in open position, no oil can enter the valve body as the valve 8 will prevent this.

From the foregoing it will be seen that when it is necessary to refill the bottle or reservoir, the lever 24 is released from the latch 25 and moved inwardly so that its lower end will move out of engagement with the lower end of the stem 17 and thus the spring 19 will move the valve 15 upon its seat to prevent oil from entering the well 12. This downward movement of the stem 17 frees the stem 9 and valve 8 so that when the pump is operated oil will be pumped from the tankup through the pipe 1 and through the pipe 2 into the part 6, forcing the valve 8 off its seat and thus the oil will enter the reservoir through the cap. Air displaced by the oil entering the bottle will be vented from the top of the bottlethrough the pipe 26 which passes through the neck or mouth of the bottle and through the cap and a part of the body with its lower end curved and located in the well so that the oil in the well will cover the lower end of the pipe. Of course the air forced from the bottle by the oil entering the same, will cause the air to pass through the vent pipe 26 and will thus bubble up through the oil in the well, and the oil covering the lower end of the vent pipe, will seal the lower end of the pipe.

When sufficient oil has been pumped into the bottle, the pumping operation is stopped and the spring 11 will force the valve 8 back upon its seat and then the lever 24 is swung outwardly and held in this position by the latch 25 so that the lower end of the lever will push the stem 1''] upwardly and thus raise the valve 15 off of its seat so that oil can pass from the bottle into the well in the usual manner.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having thus described our invention, what We claim as new is:-

1. Means for refilling a barometric feed reservoir from a tank comprising a valve body, a cap attached thereto for receiving and sealing the mouth of the reservoir, a constant level liquid receiving well positioned to receive liquid from and to thus seal the discharge end of the valve body, a spring pressed valve for preventing the oil passing from the body to the well, manually operated means for opening the valve, a pump connected with the tank, a pipe connecting the discharge of the pump with the body, a spring pressed valve normally closing communication between the last mentioned pipe and the body and opening under the pressure of oil from the pump, said valves being so constructed and arranged that the last mentioned valve is held closed when the first mentioned valve is in open position and means for venting said reservoir during the filling operation.

2. Means for refilling a barometric feed reservoir from a tank comprising a valve body, a cap attached thereto for receiving and sealing the mouth of the reservoir, a constant level liquid receiving Well positioned to receive liquid from and to thus seal the discharge end of the valve body, a spring pressed valve for preventing the oil passing from the body to the well, manually operated means for opening the valve, a pump connected with the tank, a pipe connecting the discharge of the pump with the body, a spring pressed valve normally closing communication between the last mentioned pipe and the body and opening under the pressure of oil from the pump, said valves being so constructed and arranged that the last mentioned valve is held closed when the first mentioned valve is in open position, means for venting said reservoir during the filling operation, said venting means consisting of a pipe leading from the top of the reservoir through the valve body and into the well and having its lower end terminating adjacent the bottom of the 7 well.

3.
